first embodiment

[0020]With reference to the drawings and in particular to FIGS. 1 and 2, a media sharing device constructed in accordance with the present invention is generally designated at 100. The media sharing device 100 comprise at least one data bridge device 10, which is not limited to any specific configuration. In accordance with the present invention, the data bridge device 10 comprises at least one data exchanger 11 and at least one pair of USB controllers 12, 13. The data exchanger 11 provides a function of converting media data, such as displayed image, keyboard, cursor, and sound, into USB data format. The USB controllers 12, 13 are respectively connected to two terminals of the data exchanger 11. The USB controller 12, 13 are also respectively connected to a USB interface receptacle 210 of a computer 200 and a USB interface receptacle 310 of another computer 300, so that the computers 200, 300 may carry out bi-directional transmission of data of displayed image, keyboard, cursor, an...

second embodiment

[0030]Referring to FIG. 4, a media sharing device constructed in accordance with the present invention, also designated with reference numeral 100, is shown, wherein the data exchanger 11 comprises an exchanger unit 111 and a microprocessor unit 112. The exchanger unit 111 has two terminals that are respectively connected to and between two USB controllers 12, 13 to carry out bi-directional data exchange between the two USB controllers 12, 13. The microprocessor unit 112 is connected to the exchanger unit 111 to take control of timing and route of data exchange by the exchanger unit 111.

[0031]Referring to FIGS. 5 and 6, which demonstrate a preferred application of the media sharing device 100 according to the present invention, wherein both computers 200, 300 are notebook computers that are each provided with the switching control module 20, the USB interface receptacle 210 of the computer 200 and the USB interface receptacle 310 of the computer 300 are respectively connected by USB...

third embodiment

[0036]Referring to FIGS. 7 and 8, a media sharing device according to the present invention, also designated at 100, is shown, wherein the activation device 213′ is made in the form of an application program of window-inserted dialog box. The activation device 213′ is connected to the application program 220 of the computer 200 and the application program 320 of the computer 300, whereby through the contact and activation of a virtual pushbutton 213b of the activation device 213′ (see FIG. 8), a controlling side control instruction in the form of an activation signal 213a is applied to the application program 220 of the computer 200 or the application program 320 of the computer 300, to switch the positions of the controlling side and the controlled side of the computers 200, 300n.

Abstract

A media sharing device includes a data bridge device and two switching control modules. The data bridge device has two terminals connected to USB interface ports of two computers and provides bi-directional transmission of media of displayed image, keyboard, cursor, and sound of the computers in USB data format between the computers. Switching control modules are mounted in the computers and are activated by an associated activation device to switch the controlling side and controlled side of the computers. The controlling side computer transmits data of displayed image, keyboard, cursor, and sound to the controlled side computer for computer display, executing the displayed image, keyboard, cursor, and sound supplied from the controlling side computer, or the activation device of the controlled side computer is activated to issue an instruction to the controlling side computer to switch the controlling side and the controlled side of the computers.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a media sharing device, and in particular to a device that is applicable to sharing media, such as image, keyboard, cursor, and sound, between at least two computers and comprises an activation device for activating switching of positions between a controlling side computer and a controlled side computer.[0003]2. The Related Arts[0004]A conventional connection architecture between computers only functions for transmission of data. A bulky, complicated and expensive servo network must be adopted for transmitting and sharing media, such as image, keyboard, cursor, and sound, from one computer to another computer. This requires a high system cost and complicated construction of network. Further, interactive operation of media, such as image, keyboard, cursor, and sound, between the computers may only be executed through the servo. This makes the interactive operation very difficult and may ...
